Dedicated pins for Dual Channel DDR4 memory, including channels A and B, address pins, data lines (Data ), and differential data strobes (DQS).
The AM4 socket uses a Pin Grid Array (PGA) design. Unlike Intel’s LGA (Land Grid Array) where the pins are on the socket, AM4 places the pins on the motherboard socket. The pinout diagram is typically viewed from a (looking at the socket on the motherboard before the CPU is installed). am4 pinout diagram
The AM4 socket relies on a complex network of signaling. Here are the key signals described in typical AM4 socket layout guides: Signal Group Key Signal Types Description MA/MB_DATA[63:0] Data bus for DDR4 memory, 64-bit width per channel. DRAM Control MA/MB_ADD[13:0] Row and Column address lines for memory addressing. DRAM Timing MA/MB_CLK_H/L[3:0] Differential clock signals to synchronize DIMMs. DRAM Error MA/MB_CHECK[7:0] Dedicated pins for Dual Channel DDR4 memory, including
